Slingshot homolog-1 mediates the secretion of small extracellular vesicles containing misfolded proteins by regulating autophagy cargo receptors and actin dynamics.

Increasing evidence indicates that the accumulation misfolded proteins in Alzheimer's disease (AD) arises from clearance defects in the autophagy-lysosome pathway. Misfolded proteins such as Aβ and tau are secreted in small extracellular vesicles (i.e.

Risk of corneal epithelial defects with and without postoperative erythromycin ointment after laser photocoagulation for retinopathy of prematurity.

Purpose: We aim to compare the incidence of corneal epithelial defects after laser for retinopathy of prematurity (ROP) with and without the use of postoperative erythromycin ointment.

Methods: In this retrospective observational cohort study, a total of 100 infants (200 eyes) consecutively treated with laser for ROP between 2012 and 2018. The primary outcome was presence or absence of corneal epithelial defect using fluorescein on bedside examination within the first week following laser for ROP.

Are systemic antibiotics required during and after dacryocystitis-related dacryocystorhinostomy?

Purpose: To compare the outcomes of patients with and without a history of dacryocystitis that undergo dacryocystorhinostomy without systemic intra- and post-operative antibiotics.

Methods: A retrospective review was performed to identify all cases of patients that received surgery under this paradigm and had at least three months of follow up care. Key demographic and outcome data were captured, and a statistical analysis was performed via a dedicated software package (Microsoft Excel, Redmond, WA).

Spinal Cord Stimulation for the Treatment of Chronic Pain Reduces Opioid Use and Results in Superior Clinical Outcomes When Used Without Opioids.

Background: Chronic pain causes a significant burden to the US health care system, is difficult to treat, and remains a significant contributor to increased opioid use in the United States. Spinal cord stimulation (SCS) has been FDA approved for the treatment of chronic pain.

Objective: To evaluate the hypothesis that SCS reduces opioid use, and alone maintains clinical outcome measures of pain and psychosocial determinants of health.

Safety of Spinal Cord Stimulation in Patients Who Routinely Use Anticoagulants.

Objective: We assess the safety of performing the epidural placement or revision of spinal cord stimulation (SCS) in patients whose anticoagulation has been held (termed "anticoagulant-suspended" patients) in accordance with the 2017 Neurostimulation Appropriateness Consensus Committee (NACC) guidelines.

Subjects: Patients undergoing SCS were included in this institutional review board-approved study.

Design: A retrospective analysis of a prospectively collected database was performed.

Pain Remission at One-Year Follow-Up With Spinal Cord Stimulation.

Objectives: Spinal Cord Stimulation (SCS) is an effective treatment for chronic pain. How often pain remission follows SCS has not been evaluated. This is a retrospective analysis of patients who underwent an implantation of spinal cord stimulators for various chronic pain conditions.

Enhanced tau pathology via RanBP9 and Hsp90/Hsc70 chaperone complexes.

Accumulation of amyloid β (Aβ) and tau represent the two major pathological hallmarks of Alzheimer's disease (AD). Despite the critical importance of Aβ accumulation as an early event in AD pathogenesis, multiple lines of evidence indicate that tau is required to mediate Aβ-induced neurotoxic signals in neurons. We have previously shown that the scaffolding protein Ran-binding protein 9 (RanBP9), which is highly elevated in brains of AD and AD mouse models, both enhances Aβ production and mediates Aβ-induced neurotoxicity.

Isolation and Proteomic Analysis of Microvesicles and Exosomes from HT22 Cells and Primary Neurons.

Exosomes and microvesicles are extracellular vesicles (EVs) released by most cell types. The role of EVs as a method of intercellular communication has led to these vesicles becoming a major area of interest in a variety of scientific fields including neuroscience. Emerging evidence is now demonstrating that the biomolecular composition of EVs, especially exosomes, can play a role in the progression of disease including various neurodegenerative diseases and cancer.
